Because you're aware of the temperature danger zone, you would discard any food that has been held at 120°f for more than hours. a. four b. three c. two d. six

The correct answer is option A, that is, four hours.

Explanation:

The temperature of the food in between 41 and 135 degrees Fahrenheit is considered as the temperature danger zone. The growth of the majority of the bacteria takes place in between 70 and 125 degrees F. The more the food stays in this temperature zone, the more is the threat of the bacteria to start to grow on the food.  

The general rule to keep the food out of the temperature danger zone is that if the eatable food has been in the temperature danger zone for two to four hours then one should eat it instantaneously, however, it is better to throw or discard the food, if the food is present in the temperature danger zone for the period of more than 4 hours.
